Discovery of Nuclides Project

Discovery criteria:

We decided on two main guidelines for the claim of discovery of a nuclide:
(1) Clean identification, either by decay curves and relationships to other known isotopes, particle or γ-ray spectra, or unique mass and Z identification.
(2) The discovery had to be reported in a refereed journal.

In most cases the discovery is easy to determine. However, there are many cases which are controversial for many different reasons.

We would appreciate any help in resolving the controversial cases. If you have any information that might be helpful or if you disagree with an assignment please send an email.
